Average Availability For Each Custom Table In A Report?

bharris1

I'm working on a report and had a question.  Is there a way to create an "average" line at the bottom of each table of a custom report?  For example, I have a custom tables on the report that have a few nodes each.  Is there a way for Report Writer to calculate the average availability percentage of the custom table?  I have created a quick mockup in Paint that is attached below. Currently, I've had to export it to Excel and average it manually.

Not as a part the same table as the more granular data, unless you know some SQL wizardry I've never seen before to have a single query generate grouped and ungrouped data inline.  For that type of request I tend to make a separate table just above with the aggregated values I want.  Not as slick in terms of presentation and space, but if it's a big deal for the client I shift into using SSRS since you can make that look like anything we want.
